SPARK                NEA-0468/01 Tested

Machines used:
Package-ID     Orig.Computer                       Test Computer
NEA-0468/01    IBM 370 series                      IBM 370 series

3. NATURE OF PHYSICAL PROBLEM SOLVED - The time-dependent multigroup 1-dim, 2-dim, or 3-dim diffusion equation with heat transfer and feedback is solved using the quasi-static method.


4. METHOD OF SOLUTION - A shape function is calculated at a series of time intervals. The point kinetics equations are used to give an amplitude factor between these intervals.
